A road rage incident turned violent Thursday night near Boston Common, police said.

Boston police were called to the area of the Common at about 11:49 p.m. for a report of a person stabbed. When officers arrived, they found a group of four people, all of whom were injured, according to a department spokesman. 

The people involved had a variety of injuries, including one person with a superficial stab wound on their abdomen and another with a stab wound to their hand, the spokesman said. There was also a broken wrist and a bloody mouth from being punched in the face.

The group told police that they were walking across Park Street when they saw two groups of people involved in a road rage incident and they attempted to intervene, the spokesman said. As they did, one of the groups attacked them, they told police. 

Police have not made many arrests in connection to the incident.
